No signal i plug my cable wire in from the wall and it says i have no signal and the DVT it says to Scan my channels and when i do it says 0 channels detected. just bought the Akai flat tv last night

Depends on type of tv
Usually on remote go to menu , channels (and click on the correct signal input, cable etc) then select scan or search This will detect the channels available Sometimes takes a while so be patient Hope this is help for you Good luck!

If you are receiving a "No Signal" error message, verify that:

1. All of the cables physically connected to the TV and the input device are secure.
2. The input device is turned on.

Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:

1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
2. If the TV input is not selected, press INPUT until the TV input mode is selected.
3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
4. Highlight Tuner Mode and select the correct option:
   • Antenna-over-the air signals from an antenna
   • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
5. Select Auto Search or Auto Channel Scan. (This varies by model.)
6. When the search reaches 100% complete, exit to the menu.
7. Check the available channels:
   • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
   • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.

If this does not resolve the issue, power cycle the TV and then re-run the channel scan:

1. Turn off the TV.
2. Unplug the TV from the electrical outlet.
3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
4. Release the power button.
5. Plug the TV back into the electrical outlet.
6. Turn on the TV.

Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.

1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

This television would benefit from an hdtv indoor outdoor amplified antenna not obstructed by trees, aluminum, bricks, and etc. Make sure the signal type is air and not cable and complete a channel scan during primetime tv hours after connecting to this antenna. Buy a large one that you can mount to the wall usually in a large flat box on the shelf in the store. Philips has one sold at Walmart.

Reboot ur DirectTv box.By unplug,replug it and hour later to let the box upgrade it solfware.Go to ur tv menu setup rescan it again for all the channels.It should work now.

cable or Ant.. ? after the scan if there is no channels found (0 digital, 0 analog) then try with cable or Ant to see if any of them work.. if they still don't pick up any channels and the whole yellow progress line goes across.. then it sounds like the tuner on the tv is bad.. and the tuner is part of the main-board so the whole main-board will have to be exchange or repair.. contact Amergence technology they are a 3rd party repair center that service Olevia TV's and they will be able to give you an idea on the repair cost..

try hooking up rabbit ears attenna ...then re scan channels also then should not be any analog channels only digital..... good luck

You gotta have a way to get signal to the tv . If you don't want a outside antenna use rabbit ears .After you hook them up hide them behind the tv then do a channel scan. If you don't pick up all the stations set them on top and scan again or get satillite or cable hd boxes.

In your menu from your remote you should be able to find a search mode that you can manually select. at that point you should be able to select source and start a search.

i had the same damn problem for 3 long hours but i found a solution i have olevia 32 inch tv (720). all you gotta do is go to menu>setup>tv>auto channel search> cable> standrad search
